The Iliad is one of those books which can be made or broken by the narrator. With this rendition, Anthony Heald has immediately joined my list of favourites (Patrick Tull, Nigel Lambert, Stephen Fry..) He breathes life into every one of the characters and more than makes up for any quibbles you might have with the translation.
I did not quite like the Butler translation read by Lescault. Butler uses Roman names for Greek Gods, and Lescault's narration is rather bland. Heald injects so much energy that you'd find a grocery list interesting (and to be frank, there are bits of the Iliad which are pretty grocery-like in character)
As for the book - well, it's the Iliad! A magnificent crusty old monument whose shadow falls across Western literature through the ages... well worth your time.
This course is an excellent introduction and overview of world mythology. It covers a lot of ground, and does it well. While I would recommend it to anyone, I need to add the following caveats:
Because it covers so much ground, it moves as a very brisk speed, and in some cases I would have preferred to get more depth (for example, more detail on some of the hero myths, and more discussion of the psychological interpretation of myth, a la Rank, Jung and Campbell). Dr. Voth did a really good job of covering the material, but there's enough here for two or even three lecture series.
Second, I found my interest waning slightly in during the latter part of the course. This may have been because (while he never says so) Prof. Voth seems to be suggesting a kind of monomyth for trickster myths (similar to the monomyth of the hero). While I thought the argument and evidence presented for the hero monomyth was compelling, it seemed that the trickster myths were much more diverse (hard to see an parallel between the Norse Loki and the African Anansi as presented here, for example).
Still, the course material was very engaging, and I will definitely be broadening my study of mythology as a result.
